r0 ALL WHOM IT MAY CONCERN:

Be .it known that I, LEVI S'. FALES, of Tarrytown, in the county of Wcstchester, and State of New York,

haveinvcnted a new and improved Fertilizer, and I do hereby doclarc that. the following is a full, clear, and

exact description of the same. I

The object of this invention is to provide a concentrated manure which will exert a more beneficial and stimulating action upon the growth of plants and vegetables than the so-called poudrette and other similarartificial fertilizers hitherto in use.

to a dry and pulverulent condition.

The invention consists in the combination of night-soil, charcQaL'sulphate of ammonia, bones, dried blood, and saltpetre, in such proportions as to secure an inodorous compound, which is not only highly nitrogenous in its nature, but which also contains a due proportion of the-most desirable soil-enriching mineral constituents.

To enable others to understand the nature of" my invention, I will proceed to describe its composition and mode of manufacture. I

In making my fertilizer, I take any desired, quantity of night-soil and add thereto snfiicient waste acid from petroleum-refineries to neutralize whatever free ammonia may exist therein, after which, to each ton of night-soil is added a quantity, say, about two (2) barrels of. charcoal, preferably that made from peat, sufiicient to absorb other odorous gases, such, for instance, as sulphuretted hydrogen. With this mixtureis mingled a quantity equal to ten per cent. of its weight of sulphate of ammonia, formed preferably from the waste ammoniaeal water of gas-works and the'wastc acid of petroleum-refineries; also two hundred and fifty (250) pounds of pulvcrized'boncs, one hundred (100) pounds of d ied blood, and fifty (50) pounds of saltpet-r'e'; the whole mass being thoroughly mixed or commingled by any suitable means, and afterwards dried in shallow pans until reduced The ammonia and other mal-odorons gases be 7 the fertilizer is rendered quite inodorous, while the highly-azotize'd nature, not only of the organic matter contained therein, but of the sulphate of ammonia and saltpctre, renders the compound very rich-in nitrogen, the requisite proportion of the most desirable mineral or inorganic fertilizing constituents being'furnished for the most part by the pulverized bones and the elements of the sulphate of ammonia ainl'saltpctro.

' I do notpropose to limit myself to the precise specified proportions of the several materials set forth, as the said proportions may, when desired, be changed to some extent.

What I claim as my invention, and desire to secure by Letters Patent, i's- The fertilizer, formed by the combination of the several specified materials, substantially as herein set forth. I LEVI s. FALES.
